being good looking, in good shape and having normal social skills I can readily answer this.
you get a lot less opportunities in RL because you dont know right off the bat who is looking and who isnt, thus you waste time separating wheat from chaff
secondly, you have to go look for them. whereas in online dating - they are ALL looking, and they are all brought to you already. this makes it for a much more efficient, hassle free experience.
especially if you're just looking to fuck.
I have to agree with this. Internet dating >>> standard dating for the most part. Trolling bars, parks, grocery stores, meetup groups, etc for "dates" basically involves a massive waste of time, unless you're someone that enjoys interaction that goes nowhere 90% of the time. You spend 10-30 minutes breaking the ice only to find out they a) have a boyfriend, b) aren't interested, c) live with their parents, d) have kids, e) are religious, or f) insert whatever deal breaker you want here. On online dating you can immediately filter out Jesus freaks, women who have kids, etc. It's a massive time saver.
Personally IMHO, the biggest negatives to online dating are:
a) "New toy syndrome"-- You started dating a chick and now even a hotter, "better sounding match" has started emailing you. This degrades your enthusiasm for the chick you started to see
b) It's far easier to line up multiple dates, but this actually works to your detriment. At least for me, say I set up four dates in a week and I really liked two of them for different reasons. After a few more dates with these two, a fight ensues in your head as to which one to continue with, and which one to let drop off you radar. You make a choice and then a week later shit goes south with the one you picked, and you've screwed the pooch with the other. Now you're back at square one.
Traditional dating doesn't suffer as much from the above because of the effort involved, and the fact that unless you spend a massive amount of time socializing and hitting on chicks, you simply aren't usually confronted with as much choice/opportunity that you get via online dating.
P.S: Khane, to clarify I didn't "demand" a cell phone pic. There are totally ways to do it without coming off as a creeper. Usually you don't even have to ask, just send her a spontaneous candid photo of yourself taken while in the car or something along with an offhand joke like "sorry, this is the only cell phone pic I have where I'm not topless in my bathroom", and she'll usually reciprocate.
